MACHINE FOR FORMING BOTTLE-NECKS.

SPECIFICATION forming part of Letters Patent No. 631,585, dated August22, 1899.

Application filed January 11, 1899. Serial No. 701,833. (No model.)

To aZZ whom it may concern:

Be it known that I, ALEXANDER J. RU- DOLPH, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Machinesfor Forming Bottle-Necks, of which the following is a specificatiom Theinvention relates to that class of machines which are provided withmechanism adapted to contact the neck of a bottle while it is in aheated or ductile condition and size and shape the exterior and interiorsurfaces of the same.

The object of the invention is to provide a simple, economical, andefficient machine for sizing and forming or shaping bottle-necks; andthe invention consists in the features,combinations, and details ofconstruction hereinafter described and'claimed.

In the accompanying drawings, Figure 1 is a side elevation of one formof machine constructed in accordance with my improvements; Fig. 2, asectional elevation of a portion of the machine, taken on the line 2 ofFig. 3, looking in the direction of the arrow; Fig. 3, afront elevationofa portion of the mechanism shown in Fig. 2; and Fig. 4, a sectionalview of a portion of the mechanism, taken on the line 4 of Fig. 3,looking in the direction of the arrow.

In constructing a machine in accordance with my improvements I use ahead-stock A of the desired size, shape, and strength to hold theoperative and other mechanisms in position for use, and which may bemounted upon a bench or standard A. In this head-stock is mounted arotatable mandrel or spindle B, provided with tight and loose pulleys band b for the purpose of transmitting power and motionto the rotatablemandrel.

For the purpose of sizing and forming the neck of a bottle C a disk orsimilar element D is provided .and mounted upon the tubular extension 11of the rotatable mandrel, so as to rotate therewith. Upon this disk aretwo centrifugal levers E and E, pivotally secured thereto, so as tooscillate in a plane coincident therewith, and carryingat their innerends forming-rolls e, which are rotatably mounted thereon and which whenbrought into contact with the bottle-neck give unto the exterior surfacethereof the desired size and shape. The outer ends of these centrifugallevers are provided with weights e, ad-

thereof and also provide for the requisite size of the bottle-neck.

To assist in forcing and holding the centrifugal levers against the stopmechanism an operating-sleeve H is provided, which has a shoulder orsimilar element h, secured thereto, provided with two cam-shapedprojecting rods h, which extend out from the face thereof, so that asthe operating-sleeve is moved forwardly the cam-surfaces h of theseprojecting rods contact the centrifugal levers and force them over andhold them against the stop mechanism, thus assisting in the operation ofthe forming-rolls, so as to size and shape the exterior of thebottle-neck. The backward movement of the operating-sleeve during thenon-rotation of the rotatable mandrel permits the centrifugal levers tobe operated, so as to withdraw the rolls from the bottle-neck.

To shape the interior of the bottle-neck and assistin the forming ofthelip thereof, a forming-plug I is provided, having a cylindricalportion '5 inserted in the axial opening of the tubular extension of'therotatable mandrel and which is provided with an elongated slot 11 in oneportion thereof, through which a pin 2' is passed, said pin beinginserted in the operating-sleeve, so that as the operatingsleeveapproaches the forward limit of its motion it pushes the forming-plugforwardly, so that its shoulder i may contact the bottle-lip and curl upthe same, so that it can be operated upon by the forming-rolls. Theforming-plug is preferably provided with two longitudinal rolls iadapted to contact the interior of the bottle-neck and size and shapethe same.

To assist in holding the parts in the desired position, a standard K isprovided, in which is rotatably mounted a supporting-disk lc,havingperforations through which the cam projections h are passed.

To move the operating-sleeve backwardly and forwardly, a bell-cranklever L is provided, which has a yoke portion Z, engaging with anannular groove 7L3 in the operatingsleeve. A connecting-rod Z isprovided, which may be secured to a treadle or similar element (notshown) for the purpose of moving the bell-crank lever.

1. In a machine of the class described, the combination of a rotatablemandrel, a disk or similar element mounted thereon so as to rotatetherewith,and forming-roll mechanism pivotally mounted on the disk andarranged to be operated toward or from the center of the disk bycentrifugal force and size and shape the interior of the bottle-neck,substantially as described.

2. In mechanisms of the class described, the combination of a rotatablemandrel, a disk or similar element mounted thereon so as to be rotatedthereby, lever mechanism pivotally secured to the disk so as tooscillate in a plane coincident with the plane of rotation of the diskand provided with forming-rolls arranged to be moved toward or from thecen ter by centrifugal force when the disk is rotated, substantially asdescribed.

3. In a machine of the class described, the combination of a rotatablemandrel, a disk or similar element mounted thereon so as to be rotatedthereby, two levers pivotally secured to the face of the disk so as tooscillate in a plane coincident with the plane of rotation of the disk,a forming-roll secured to the inner end of each lever, and a weightsecured at or near the outer end of each lever and arranged so as tooperate the forming-rolls by centrifugal force when the disk isrotated,substantially as described.

4. In a machine of the class described, the

combination of a rotatable mandrel, a disk or similar element mountedthereon so as to be rotated thereby, two levers pivotally secured to theface of the disk so as to oscillate in a plane coincident with the planeof rotation of the disk, forming-rolls secured to the inner end of eachlever, a weight secured at or near the outer end of each lever andarranged so as to operate the forming-rolls by centrifugal force whenthe disk is rotated, and stop mechanism to limit the movement of thepivotal levers in one direction, substantially as described.

5. In a machine of the class described, the combination of a rotatablemandrel, a disk or similar element mounted upon the mandrel so as to berotated thereby, a lever or levers pivotally secured to the face of thedisk so as to oscillate in a plane coincident with the rotation thereof,a forming-roll on the inner end of each lever, a Weight on the outer endof each lever, stop mechanism to limit the movement of the levers in onedirection, and means for forcing and holding the levers in engagementwith the stop mechanism, substantially as described.

(3. In a machine of the class described, the combination of a rotatablemandrel, a disk or similar element mounted upon the mandrel so as to berotated thereby, a lever or levers pivotally secured to the face of thedisk so as to oscillate in a plane coincident with the rotation thereof,a forming-roll on the inner end of each lever, a weight on the outer endof each lever, stop mechanism to limit the movement of the levers in onedirection, an operating-sleeve provided with forwardly-projecting pins71/ arranged to contact the pivoted levers and force and hold the sameagainst the stop mechanism, substantially as described.
